Prospects for the convergence of polyphenols with pharmaceutical drugs in Type 2 Diabetes: challenges, risks, and strategies.

Type 2 diabetes mellitus (T2DM) is a complex disease that can lead to a variety of life-threatening secondary health conditions. Current treatment strategies primarily revolve around tight glucose control that is difficult to achieve and often turns out to be dangerous due to possible hypoglycemic events. Numerous long-term studies have demonstrated that complex pathways, including low-grade inflammation due to fluctuating glucose levels, are involved in the progression of the disease and the development of secondary health conditions. Growing clinical evidence supports the effectiveness of using multiple medications, possibly in combination with insulin, to effectively manage T2DM. On the other hand, despite the huge, largely untapped potential therapeutic benefit of 'polyphenols', there remains a general skepticism of the practice. However, for any evidence-based clinical intervention, the balance of benefits and risks takes center stage and is governed by biopharmaceutics principles. In this article, we outline the current clinical perspectives on pharmaceutical drug combinations, rationale for early initiation of insulin, and the advantages of novel dosage forms to meet the pathophysiological changes of T2DM, emphasizing the need for further clinical studies to substantiate these approaches. We also make the case for traditional medicines and their combinations with pharmaceutical drugs and outline the inherent challenges in doing so, while also providing recommendations for future research and clinical practice. Significance Statement Type 2 diabetes is associated with life-threatening secondary health conditions that are often difficult to treat. This review provides an in-depth account of preventing/delaying secondary health conditions through combination therapies and emphasizes the role of effective delivery strategies in realizing the translation of such combinations. We will build the case for the importance of polyphenols in diabetes, determine the reasons for skepticism, and potential combinations with pharmaceutical drugs.
